Ash and his friends see a Zapdos.
Ash reverts to human form after his transformation.
When James says "Time to say adieu!", Meowth sings "To you, and you, and you and you and you!" to the tune of the song So Long, Farewell from the musical film The Sound of Music (1965).
Jessie breaks the fourth wall in this episode by asking James to explain their mecha to their "viewing audience".
The concept of this episode, as well as the appearance of the Electric-type member of a legendary trio, is somewhat similar to The Legend of Thunder!, which focused on Raikou. It is also believed that Professor Sebastian's Miracle Crystal System was made from the crystal seen in this episode. It is also implied that the crystal must have been stolen from the lake by Sebastian and his minions.
